Met him this evening...
Super nice dude. Good taste in movies. Came into a local reportory theatre where I volunteer, dressed very low key. And while I recognized him from numerous television appearances, I could not put my finger on why he looked so familiar. When I asked him about his work, he mentioned several of his more recent efforts, but they weren't where I remembered him from. Then I realized, it was Star Trek TNG! He was only ever in one episode, but I've probably seem all of them dozens of times.
I wonder if he realizes the impact that character had? Neat.
